OBSTETRICAL FORCEPS.

SPECIFICATION forming part of Letters Patent No. 733,402, dated July 14, 1903.

Application filed January 21, 1903- Serial No. 139,992. (No model.)

To all whom, it ntrty concern:

Be it known that I, HENRY E. KOCH, a citizen of the United States, residing at Hartington, in the county of Cedar and State of Nobraska, have invented certain new and useful Improvements in Obstetrical Forceps; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to obstetrical instruments for use upon animals generally, but is especially adapted to be used in veterinary surgery and particularly in the parturition of sows.

The various features of the invention are illustrated in the accompanying drawings, in which- Figure 1 is a plan view of one form of the device with the clamps or jaws open, dotted lines showing their position when closed. Fig. 2 is a side View of the same with the jaws closed; Fig. 3, an enlarged cross-section on line 00 a: of Fig. 1. Fig. 4 is a side view of a modified form of the device, showing the sides of the two members, one above the other; and Fig. 5 is a reduced plan of the modified form of the device with its jaws closed and with the rod, jaw, and lover located on the side of the body opposite to that shown in Fig. 4..

Like letters denote corresponding parts in the several views.

The letter A indicates the elongated fiattened body of the forceps, having the handle a and point a made integral with the handle.

13 B are tubes extending from near the end of the handle to near the end of the point.

C C are rods extending through the tubes B, and near the point are formed into blades or jaws c 0, whose ends are adapted when closed to touch or to pass each other. The other ends of the rods are bent upward to form short levers d or are bent over forward to form triangular loops D D, the ends of the rods at the front angle being secured to the rods through openings 1) b in the tubes B. A

slide-ring E on the loops D D holds the loops, and with them the jaws c c, in operative position, one of the loops having notches d to prevent slipping of the ring.

This device is to be used when parturition is delayed or is proceeding abnormally to seize a foot or the nose of the fetus and assist its delivery by drawing it forth.

In the modification shown in Fig. 4, the ring E is fixed by passing it through an eye a on the body or handle of the forceps, and an auxiliary member F is provided, which has the same general construction as the forceps above described, but with a. single tube and rodtherein and with the lever d instead of the loop D. It is immaterial on which side of the body F the single rod, jaw, and lever are located, the figures of the drawings showing them in either position. This member is inserted loosely in the ring E, which serves as a fulcrum in operating the two members at once, its purpose being to afford the operator additional hold on the fetus when the grasp of the other form is insuflicient to effeet a delivery.

Having described the invention, what I claim is 1. A forceps having a flattened body and handle thereon, tubes extending from near the end of the handle to near the point, rods in said tubes,jaws on said rods near the point, loops on said rods at the handle, a slide-ring on said loops, and notches on a loop to engage said ring, as herein set forth.

2. A forceps having a flattened body and handle thereon, tubes extending from near the end of the handle to near the point, rods in said tubes, jaws on said rods near the point, levers on said rods near the end of the handle, an eye on the forceps, a ring through said eye, and an auxiliary member having a single tube, rod, jaw and lever, of the kind above described, and adapted to be loosely inserted in said ring, for the purposes stated.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY E. KOCH.
